While the Westside's 17th Street and Broadway projects never quite reached the construction stage after being selected for the city's Neighborhood Traffic
Management Program (NTMP) in 2005, eight calming projects elsewhere in the city (including Holland Park) have been completed in that time.
Here is information on those other projects, as provided by Kristin Bennett, the NTMP coordinator:

Bayfield/Oak Creek Drives - selected in 2006; construction of a portion of their neighborhood traffic calming plan - two treatments completed after Colorado
Springs Utilities line maintenance work and one completed by a developer. Remainder of project has been cancelled due to the NTMP elimination.
